SEPARATOR FOR SPINNING-FRAMES.

SPECIFICATION forming part of Letters Patent No. 526,010, dated September 11, 1894. Application filed December 23, 1893. Serial No.494,976- (No model.)

To all whom it may concern.-

Be it known that we, GEORGE A. DRAPER and GEORGE O. DRAPER, both of Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Separators for Spinning-Frames, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

Many different kinds of separators have been devised for use in connection with ring spinning and twisting frames to prevent the yarns from catching one against the other in case the yarns bow out or balloon as it'is called, said separators being raised by or through the action of the ring rail, or in unison with said rail, by difierent mechanical appliances. When the bobbins have to be doffed from the spindles the separators are commonly turned up and back out of the way by hand. It is a desideratum, when doffing the frame and at other times under certain conditions, to be able to push the separators back out of place from between the bobbins or spindles, and this invention has for its object the production of a separator mechanism which has that capacity, and which may be pushed back into its abnormal or inoperative position by pushing from the outside of the frame, where the operator stands, inwardly.

One part of this invention, therefore, consists in a separator carrier bar and its attached arms, combined with a fulcrum, said arms and fulcrum being constructed in such manner as to enable one to be moved on or with relation to the other, whereby a bar with its attached separators may readily be pushed backwardly and the separators be thereby removed from between the spindles.

Figure l in section shows a sufficient portion of a spinning or twisting frame with the improvements comprehended in this invention added to enable the same to be understood; Fig. 2, a view of the same parts but in a different position. Fig. 3 is yet another view of the same parts with the separators pushed back away from the ring rail and from between the spindles and bobbins. Fig. 4. is a partial front elevation of a spinning or twisting frame, the section represented by Fig. 1 being in the line .10 Fig. 4, and Fig. 5 is a detail of one of the carrying arms for the carrier bar.

The frame-work A; the roller-beam A; the 5 5 guide-board at having guide-eyes a for the yarn or thread; the spindle-rail B; the spindle b; the ring rail 0; the ring 0, and traveler c. are and may be all as usual in ring spinning and twisting frames, so need not be herein further described. The roller-beamhas at or near each end suitable depending stands d provided each with a fulcrum 2 and with a stop or arresting device 3.

The separators e, composed preferably of thin metal have as shown a foot e which rests on acarrier bar 6 composed preferably of two rods, and at the back of said bar is a nut c ,a screw 4 being extended through said foot between said rods and screwed into said nut, the screwihus serving to fix the separators upon said carrier bar, but in an adjustable manner.

The endmost separators, designated by the letter 9, are of the same shape as the separators e, and said separators 9 have a foot g like the foot 6' of the separators e, but instead of the screw 6, see Fig. 4, which confines the separators to the carrier bar entering a nut, as described of the separators e, the said screw is made to enter a threaded hole in a lip g at the forward end of the arm g said arm, in the form in which this invention is herein embodied, having a slot 7 to embrace and slide on said pin 2, the outer end of the slot being offset, as at 8, to engage said pin when the separator carrier bar is moved back as in Fig. 3.

In practice the arms 9 one at each end of the carrier bar, but only one of which is shown at the leftin Fig. 4:, will have mounted upon them in an adjustable manneraweight w controlled as to its position by a set-screw w, the adjustment of said weight onsaid arm properly counter-balancing the weight of 5 the separators.

Viewing Fig. 1 the arm 9 is in its lowermost position and is sustained in that position by the stop 3. Now let it be supposed that the frame is started. The ring rail will too be elevated in usual manner from the position Fig. 1, and will, as it rises, strike the lower ends of the separators and will lift said separators and their attached guide-bar, the arms 9 turning on the fulcra 2, as the center of motion, and so long as theframe is running regularly the separators will be raised and lowered in usual manner. Now if it becomes necessary to doif the bobbins, or necessary for any reason that the separators be removed from between the spindles, the operator may take hold of the separators or their frame and push the same back, such pushing causing the arms g to slide on the fulcra 2 until said fulcra finally enter the notches 8 when the separators will be locked in their backward position, as in Fig. 3.

Prior to this invention it is thought that a separator carrier bar has never been so mounted that the same could be raised and lowered regularly by the ring-rail and could be pushed back at any position of the ringrail, so as to leave the spaces between the adjacent bobbins or spindles perfectly open and free from the presence of separators.

The separator mechanism herein shown is very simple in construction, is durable, is composed of'few parts, and may be easily operated.

This invention is not, therefore, limited to the exact shape shown for the arms 9 or for the fulcra 2, which not only form the center about which the arms may turn in the up and down movements of the separators, but also Having described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a ring spinning or twisting frame, a carrier-frame having a series of separators, and laterally extended rigid arms, combined with fulora or guides to sustain said arms and permit the separators to be acted upon and be raised and lowered by the ring-rail, said arms being free to be slid longitudinally across said fulcra or guides forthe purpose of removing the separators from between the spindles, substantially as described.

2. In a spinning or twisting frame, stands provided with fulcra, combined with slotted arms attached to a separator carrier-frame and engaging said fulcra, and attached separators, to operate, substantially as described.

3. In a spinning or twisting frame, stands provided with fulcra 2, and suitable stops 3; combined with slotted arms having locking notches, a separator carrier-frame, and attached separators, to operate, substantially as described.

4. The ring-rail in combination with a separator frame having a series of attached separators, and having provisions in virtue of which the same may stand normally above the ring-rail, but in virtue of which they may be moved back away from the rail when desired by the operative, said provisions comprising stationary guides and arms free to slide on or with relation to said guides, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
